    Abstract: Embodiments of the disclosed technologies provide a carrier frequency selecting method and apparatus. The method comprises: determining, by UE, whether information of a service carrier frequency sent by a base station is received, wherein the service carrier frequency is the carrier frequency to carry traffic selected by the base station when a target cell carrying the UE is a multi-carrier cell; residing, by the UE, at a carrier frequency corresponding to the information for a service carrier frequency, if so; and, otherwise, residing, by the UE, at an original camped carrier frequency. With the embodiments of the disclosed technologies, the problem that a service carrier frequency selecting strategy in related techniques is to perform selection passively and lacks initiative is solved, and a technical basis for balancing loads on carrier frequencies carrying traffic is provided and further system efficiency is enhanced for an NB-IoT system, which is mainly to transmit small data.

    Abstract: Provided are a hybrid automatic repeat request timing method and apparatus. The method comprises: in the case where a device detects physical shared channel transmission within a first target transmission time interval (TTI), the device transmitting an acknowledgement instruction (ACK) response or a negative acknowledgement instruction (NACK) response of a hybrid automatic repeat request (HARQ) of a corresponding physical shared channel within the (pre-set number)th TTI after a second target TTI, wherein the number of symbols L1 contained in a TTI for downlink data transmission and the number of symbols L2 contained in a TTI for uplink data transmission satisfy the following condition: LI∈{1, 2, 3, 4, 5, 6, 7}, I=1 or 2. According to the embodiments of the present invention, the problem in the relevant art that an HARQ timing relationship cannot satisfy the further shortening of a TTI length is solved.

    Abstract: A method and device for data transmission in a wireless communication network are provided. The method includes: in data reported by multiple transmitter nodes and received by a receiver node, when a statistical result of data reported by K transmitter nodes satisfies one of preset conditions, selecting one transmitter node from the K transmitter nodes, herein K is an integer greater than 1; the receiver node receiving data subsequently transmitted by the selected transmitter node; and the receiver node notifying unselected K−1 transmitter nodes of optimization information and the data subsequently transmitted by the selected transmitter node, herein the optimization information includes a basis for a transmitter node to determine whether to transmit subsequent data.

    Abstract: The provided are method and device for processing information interaction, the offloading processing method and device, a base station, an RNC and UE. The method for processing information interaction includes that: a target side network element for handover of UE receives at least one of the following source side information sent by a source side network element: WLAN auxiliary information, offloading rule information, WLAN measurement report information, offloading decision information and information indicating a capability in supporting interoperation with a WLAN; and/or, the target side network element sends at least one of the following target side information to the source side network element: WLAN auxiliary information, load information, offloading rule information, measurement configuration information, offloading decision information and information indicating a capability in supporting interoperation with the WLAN. According to the present disclosure, the effect of saving UE energy and network resources is further achieved.
